Abstract

PURPOSE:To easily integrate and abolish exchanges by providing a device to divide a telephone number and the accommodating position information of a telephone set and to logically hold the corresponding relation independently of respective exchanges. CONSTITUTION:An exchange 2 can communicate with a number converter 1 by using a common line signal, etc. When the accommodating position information of the telephone set to change an accommodating position and the telephone number of a telephone are sent to the number converter 1, the number converter 1 changes the corresponding data of the telephone number and accommodating position information stored in the device, and a number conversion thereafter is executed based on the data. A subscriber designates the telephone number given to the telephone set by using a specific telephone set, and further, the exchange sends the accommodating position information and telephone number of the exchange to the number converter. Thus, the telephone number of oneself can be given to any telephone set.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides an incoming call selection method, more specifically, a method for independently managing the relationship between a subscriber's telephone number and the accommodation location of an exchange, even if the accommodation location changes. This relates to an incoming call selection method that eliminates the need to change telephone numbers.

[Conventional technology]

In conventional communication networks with multiple exchanges, the telephone number is associated with the physical location of the telephone, such as which exchange and which subscriber line. This corresponding information is stored in each exchange so that the location where the subscriber line is accommodated can be selected, and the destination of the call is selected by comparing the telephone number with this data.

[Problem that the invention seeks to solve]

For this reason, if the location of the telephone equipment changes due to relocation, etc., not only will the telephone number have to be changed, but if you try to consolidate the exchange without changing the telephone number, the connection terminal between the subscriber line and the exchange will be disconnected. There is a problem in that the wiring of the connected MDF becomes complicated.

The present invention solves the above problems and allows the telephone to be transferred to different telephone stations (
You do not need to change your telephone number even if you transfer your phone number to an exchange (exchange).
The purpose is to facilitate the consolidation and abolition of switching equipment.

[Means for solving problems]

According to the present invention, the above-mentioned problem can be solved by providing information on all or part of the telephones in the communication network, in addition to the telephone number, in addition to the telephone number, in a communication network having a plurality of exchanges. A number translation device that holds data that associates the telephone number with the accommodation location information is provided logically independent of the exchange that controls switching, and the above data is controlled by the exchange or by the subscriber himself/herself. Further, all or a part of the exchange is configured to be able to communicate with the number conversion device, and when the number conversion device receives the subscriber's telephone number from the exchange, it changes the telephone number of the subscriber. This problem is solved by a terminating call selection method characterized in that the accommodating location information is sent back to the exchange, and the exchange uses the accommodating location information to select a line and connect to the terminating exchange and the terminating subscriber.

[For production]

The present invention separates telephone number and telephone accommodation location information, and provides a device that maintains the correspondence relationship logically and independently of each exchange.If the telephone accommodation location changes, this correspondence data is changed, and the exchange The destination of the call is determined by inquiring about the accommodation location information based on the telephone number.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram of a general embodiment of the invention. In the figure, 1 is a number conversion device that holds correspondence information between a telephone number and the accommodation location information of the telephone, 2 is an exchange that has a communication function with the number conversion device, and 3 is a telephone housed in the exchange 2. , 4 is a called side telephone, 5 is a called side exchange that accommodates the telephone 4, and 6 is a relay exchange. Also,
7 is a communication path between the exchange and the number conversion device. In this embodiment, the operation when making a call from telephone 3 to telephone 4 will be described. First, when the exchange 2 receives the telephone number of the telephone 4 from the telephone 3, it transmits the number to the number conversion device 1 via the communication path 7, and receives the housing location information of the telephone 4 from the number conversion device 1. The exchange 3 selects the destination exchange 5 based on this information. Because it operates in this way, for example, even if a telephone 3 housed in the exchange 2 is relocated to the exchange 5, communication to the telephone 3 can be made by simply changing the housing location information of the telephone 3 in the number conversion device 1. You can keep your original phone number. It goes without saying that accessing the number translation device is not essential for calls from telephones housed in the exchange 2 to telephones housed in the same exchange, and can be processed only within the own exchange.

Next, a method for changing correspondence data between a telephone number and accommodation location information in the number conversion device will be explained using FIG.

In the figure, the exchange 2 is capable of communicating with the number conversion device 1 using common line signals, etc.
When the housing location information of the telephone whose housing location is to be changed and the telephone number of the telephone are sent to the telephone number converter 1, the number conversion device 1 changes the correspondence data between the telephone number and the housing location information stored in the device, and Subsequent number conversion is performed based on this data. In addition, the subscriber instructs the exchange that accommodates a particular telephone to specify the telephone number to be assigned to the telephone using a specific number, and the exchange further instructs the telephone exchange that accommodates the telephone and the telephone number to be assigned to the telephone. By sending your phone number, you can assign your phone number to any phone.

FIG. 2 is a schematic diagram of an embodiment in which the present invention is applied only within a specific area. In the figure, 1 to 7 are the same as in FIG. 1, 8 is an area to which the present invention is applied, 9 is a relay exchange that relays traffic from outside area 8, and 10 is an exchange outside area 8. , 11 is a relay exchange 9 and a number conversion device 1
It is a communication channel with In this example, the operation of the exchange with respect to traffic to and from region 8 is the same as in FIG. For traffic from outside the area 8, the relay exchange 9 selects the terminating exchange 5 after inquiring the number converter 1 about the accommodation location information of the terminating telephone.

Furthermore, traffic from the telephone 3 to the telephone outside the area 8 is connected as usual without accessing the number conversion device 1. Because it operates in this manner, it is possible to relocate the telephone within the area without changing the telephone number. It goes without saying that if areas with the same local code are selected as the areas, it will be easier to process the exchanges and manage the subscribers.

FIG. 3 is a schematic diagram of an embodiment in a communication network in which exchanges to which the present invention is applied and existing exchanges coexist. In the figure, 1, 3, 4.7 are the same as in FIGS. 1 and 2, 12 is an exchange to which the present invention is applied, 13 is an exchange to which the present invention is not applied, and 14 is an exchange to which the present invention is applied. 15 is a telephone set transferred from the exchange 12 to the exchange 14; 16 is a relay exchange; 17 is a relay line from the exchange 13 to the relay exchange 16; 18 is a relay line from the exchange 13 to the relay exchange 16;
19 is a direct line between the exchange 13 and the exchange 12. In this embodiment, the format of the telephone accommodation location information is the same as the format of the telephone number consisting of the area code, local code, and subscriber number. Also,
The exchange 12 has correspondence information between the telephone number of the telephone that was transferred from the exchange to another exchange and the accommodation location information of the relocated telephone.
A function is provided to transfer calls received at the exchange 12 to the accommodating exchange at the transfer destination without going through a number conversion device outside the exchange.

In this embodiment, since the exchange 13 does not have a communication function to the number conversion device 1, calls made from the exchange 13 to the telephone 15 are not converted, and are sent directly through the direct line 19 or through the line 17. Once the call arrives at the exchange 12 via the relay exchange 18 and the relay exchange 16, the exchange 12 has a function to transfer this call, so the call is
0 or line 18.21, the call can arrive at the transfer destination exchange 14. In addition, relay exchange 1
6 also has the function of accessing the number conversion device 1,
It goes without saying that when the switching system 13 selects the trunk line 17, the call does not arrive at the switching system 12, but can be directly selected from the trunk switching system 16 to the switching system 14. Furthermore, since the format of the accommodation location information is the same as that of a normal telephone number, no special signal transfer method is required in the exchange on the called side. Because it operates in this way, the telephone set housed in the exchange 12 can be transferred to an existing exchange without a communication function to a number conversion device, while keeping the same number.

Therefore, the present invention is partially applicable even to communication networks in which existing exchanges to which the present invention is not applied exist.

FIG. 4 is a schematic diagram of a configuration example of a number conversion device applicable to the present invention. In the figure, 2 and 7 indicate exchanges and communication channels, respectively, as in FIGS. 1, 2, and 3.
22 is a common line signaling device for communicating with the exchange; 23 is a memory that holds correspondence data between the telephone number of the telephone and accommodation location information; 24 is a number controller for controlling the common line signaling device 22 and controlling the number based on the data in the memory 23; It is a processor that performs conversion. The common line signaling device 22, memory 23, and number conversion processor 24 are each duplicated to improve reliability. In the figure, when the number conversion processor 24 receives a telephone number from the exchange 2 via the communication path 7, it refers to the data stored in the memory 23 and reads the housing location information of the telephone having the telephone number. , and is sent back to the exchange 2 via the common line signaling device 22.

Note that if a large amount of communication and processing is required for number conversion, for example, multiple sets of common line signaling devices 22, memories 23, and number conversion processors 24 may be provided for each station number. It goes without saying that a building block configuration is possible. Although not shown in this figure, it goes without saying that a common line signal relay exchange is interposed between the communication path 7 and the common line signaling device 22.

FIG. 5 is a schematic diagram of an example of a configuration in which a number conversion device is integrated into a relay exchange. In the figure, 22, 23° 24 is the fourth
The same thing as in the figure is shown, 25 is the communication path device of the exchange, 26
is a signal device, 27 is a signal processing device, 28 is a bus for communication between processors, 29 is a management processor (CNP), 3
0 is a memory, 31 is a file device, and 52 is an interprocessor communication control device. Here, the common line signal device 22,
The devices other than the memory 23 and the number conversion processor 24 are devices originally installed in the transit exchange. Here, the operations of the common line signaling device 22, memory 23, and number conversion processor 24 are the same as in the embodiment shown in FIG. 4, except that the management processor 29 manages the entire system. It goes without saying that a plurality of common line signaling devices 22, memories 23, and number conversion processors 240 sets can be connected on the bus 28 to form a building block configuration depending on the scale.

FIG. 6 is a schematic diagram of an example of a configuration in which a number conversion device is combined with a common line signal relay exchange. In the figure, 25.24.
29% shows the same as Figures 4 and 5, 33 is
A common line signal device, 34 is a signal processing processor, 35 is an inter-processor communication control device, and 36 is an inter-processor communication bus. Here, the devices other than the memory 23 and the number conversion processor 24 are devices originally installed in the common line signal relay exchange. When integrated into a common line signal relay exchange, the common line signal equipment used for communication with the exchange can be the same as the equipment originally used for signal relay.

The operation of the memory 23 and the number conversion processor 24 is as follows.
It is basically the same as the embodiment shown in the figure, but when it receives a telephone number from the calling exchange, it returns accommodation location information, but at the same time it can also send a connection signal to the other exchange. This makes it possible to reduce processing at the originating exchange. In addition, a memory 23, a number conversion processor 2
Needless to say, it is possible to connect a plurality of sets of 4 on the bus 36 to create a building block configuration depending on the scale.

〔Effect of the invention〕

As described above, the present invention not only eliminates the need to change the telephone number even if a telephone is relocated, but also has the advantage that it is easy to consolidate and abolish the exchanges because there are no restrictions on the housing locations of telephone numbers and exchanges. Furthermore, in the event of a failure at a central telephone office, it is also possible to temporarily transfer the telephone number to another central office while keeping the same telephone number. Additionally, since the same area number can be assigned across different exchanges, it is also possible to eliminate restrictions on number capacity due to physical limitations, which means that in the past, when the number of subscribers increased, the number of digits in the local area code was increased. It is also possible to improve the situation. Furthermore, the present invention can partially obtain the above effects without being applied to all exchanges in a communication network.
